There are six filters stages in the DFE PRACH IP. They are enabled from the last stage first, i.e., filter stage 5 is always used and as more decimation is required, earlier filters are enabled. Unused filters are bypassed. Filter stage 5 can be configured either as a decimation by three filters or a decimation by two filters. All other stages implement decimation by 2 only.
